On the right of the British was posted the fourth division, under Sir A. Campbell, supported by Sir S. Cotton's brigade of cavalry; on their left commenced the first division, of which the Guards were on the right. The remainder of this division, consisting of Brig.-Gen. Cameron's brigade and the Germans, extended across the most open ground, and joined on the left to the brigade of Colonel Donkin and the second division, clustered round the height for its defence. The other brigade of Gen. M'Kenzie was placed in the second line. The remainder of the cavalry had bivouacked at some distance to the rear, and were not come up. The enemy were employed from daylight in placing opposite our centre thirty pieces of cannon on the opposite side of the ravine, but not a shot was fired on either side, and the whole looked as if the armies had met for a review. But the calm augured the coming storm, and the quiet evinced that all were aware of the great approaching struggle, and that it was useless to throw away a casual fire, or destroy individuals, where salvos alone and the death of thousands could decide the day. When the vast column we had seen in the dusk was considered ready, a single cannon shot from the centre of the enemy's batteries was the signal for its advance, and for the opening of all their guns. A shower of balls instantly fell on all parts of our position, and the smoke, (the wind being east, and the damp of the morning preventing its rising,) was blown across the ravine, and completely enveloped us in a dense fog. But we had seen the forward movement intended for our dislodgment, and knew, under cover of this cannonade and smoke, it was advancing up the face of the hill. It consisted of a close column of battalions, of the same division of Ruffin which had attacked the night before.
